A New Lyotropic Nematic Mesophase

  • Robert C. LongJr.

Several years ago Lawson and Flautt reported a new type of nematic phase suitable for use as an ordering solvent in NMR spectroscopy. This lyotropic phase is a quaternary system composed of sodium decyl sulfate, decanol, sodium sulfate and water, with corresponding solvent capabilities not generally exhibited by thermo-tropic liquid crystals. In addition it possesses the property, of special interest in NMR spectroscopy, that its ordering is not disturbed when it is spun in a non-solenoidal magnetic field. A number of investigators have employed this ordering medium for the determination of molecular structures and orientations of various solutes using NMR methods applicable to anisotropic media.1
